+LyX 1.6.0 introduces support for the pLaTeX distribution which provides extended
+language and script support for Japanese. The language "Japanese" now uses this
+new method. Japanese support via the CJK package is still available, but has been
+renamed to "Japanese (CJK)". Old documents continue to use the CJK method.
+Also cf. the "known issues" section for some remaining problems.
Some of the LyX functions have changed names:

+- New pLaTeX support for Japanese:
+ * Documents using this method can be backported to 1.5 in pricipal, but
+ the backported documents are not guaranteed to work, since 1.5 falls
+ back to the CJK package; expect the output to differ.
+ * pLaTeX provides a Japanese variant of BibTeX named "jbibtex", which will
+ be selected automatically by LyX. If you run into problems with this or
+ if you need to use an alternative BibTeX program, you can change this
+ setting in the LyX preferences (Output->LaTeX->BibTeX command).
